Hey everyone,
Just came across a website that is advertising the release date for the 27th of December 2013 in regards to PC, PS3 and Xbox 360 versions of the game.

Note: This came up during my searching for a Season 16 DVD release here, as I am in Australia and we are yet to get the season for purchase.
Now I'm not saying this is official or anything like that, it's just what they have written there. However I thought I would share this with you all as I am also awaiting it's arrival.
